When comparing experimental lengths and predicted lengths, our I noticed that mostly all of the experimental lengths were close to their predicted length. The only exception was the length at 1 second. This length was not even close to the absolute error. The suspected reason for this is because, in the beginning, our group was not properly swinging the pendulum at the correct time.

When comparing the increasing absolute error and the relative error values, I could not identify any significant pattern. The found values were sometimes higher and sometimes lower. No pattern or meaningful change was identified in our data.

In Graph 1 there is an obvious observation. All the values increase as the period goes up. The predicted, and experimental lengths are very close, and both …show more content…
Using the equation we could find the predicted scientific values, and compare them with ours. Our lab used many different lengths and periods; this enabled a comparison with predicted values. With multiple comparisons of raw data are used, you can come to a valid and robust conclusion.

To finish this lab effectively, we could have used more time. Our experimental lengths could have been more accurate with multiple trials. With more time we could have had more certain periods. Finally, with more time you can conduct more trials for stronger evidence.

The process of this lab was well done. However, it could have had more instructions on the procedure of the experimental aspect. It took our group a while to figure out how to measure and time the experiment. This lab was very meaningful because of the comprehension in the swinging and estimating of a pendulum. We can use this information further down the road for bigger, and more complicated labs.
The limitations of this lab included the length of the string, the difference between the ground and hanging point, the width of the measuring area, and the accuracy of stopping the timer at the right

Station 1A: Reflection (Mirrors) 1.This station shows reflection because it shows how the laser reflects off the mirrors. 2.This station does not have energy that is being absorbed. The energy in this station is not being absorbed it is being reflected off the mirror. 3.The shapes that were in this station were triangles because the laser reflected off the mirrors in a triangle shape 4.Two other examples of reflection is when you can see yourself in a bubble and also when light reflects of…

1.) Sticky ends are sites seen on single-stranded DNA or RNA molecules, having a nucleotide base sequence complementary to that of another strand. These are created when restriction endonucleases are used to unevenly cut, or cleave DNA at a specific sequence, allowing for the two strands to be connected by base pairing. These structures are produced in the laboratory with the use of restriction enzymes for cloning purposes. Scientists can choose from several places to cut the genetic sequence with…

Subnet Mask : To create the subnet mask, first remember that the purpose of the subnet mask is to separate the (32 bit) ip address into the network prefix and the host number. If a bit in the subnet mask is 1, the corresponding bit in the IP address is part of the network address; if the bit in the subnet mask is 0, the corresponding bit in the IP address is part of the host address. First depict the ip address in binary. Take 192.168.100.0 and convert to binary: ip address: 11000000…

Project 1: Lab Report Frank Johnson CHM2045L Section 001 June 5, 2018 Introduction: We discover some elements in nature that are unknown and it’s difficult to know what elements are in these compounds. We can take a random substance that is unknown from nature and figure out what it is composed of by running simple lab tests. A real-world example of this would be how doctors examine a patient’s blood to see if they have overdosed off of drugs. By using the procedures in this project 1 lab, we can…

Connector the oscilloscope to the input and output of the preamplifier circuit by connecting one probe to the female XLR input connector. Set the signal generator to 1 KHz and set the oscilloscope input probe to 10mv. Test and see if any waveform is displayed on the oscilloscope. Figure 15 is showing the input signal only and already it can be determined that the input signal is very noisy. The waveform is showing…
